Bottle Oxygen vs. Potential Density

Contours of dissolved oxygen from discrete water samples versus
sigma-theta during HOT cruises. Cruise times are indicated by the
symbols along the bottom axis. The average density of the sea surface
for each cruise is connected by a heavy line. Locations of bottle
closures are indicated by solid circles. Oxygen scale is given by the
color bar along the right side of the figure.
